Orthophoto of the Czech Republic - Klatovy 2-9

Digital seemingly seamless orthophoto of the Czech Republic in a 8-bit color scale. The pixel of the raster image Ortofota ČR displays 0.200 m (band „East), resp. 0.125 m ("West" zone) of the area in the middle plane of the terrain. The orthophoto of the Czech Republic is constantly improving its positional accuracy characterized by a mean positional error, this error ranged from 0.20 to 0.21 m in the years 2019 - 2020. The evaluation of the accuracy of the orthophoto of the Czech Republic in 2021 has not yet been completed. Orthofoto ČR is distributed in graphic raster formats JPG in dispensing units with a size showing 2.5 x 2 km of terrain in the SM 5 clade.本数据集为捷克共和国数字化无缝正射影像（orthophoto），采用8位色彩量化方案。该栅格图像Ortofota ČR的地面采样分辨率为：东区波段0.200米，西区波段0.125米，对应实地地形的平面区域。捷克正射影像的位置精度正持续提升，其以平均位置误差作为精度表征指标；2019至2020年间，该误差值处于0.20米至0.21米区间内。2021年度捷克正射影像的精度评估工作尚未完成。Orthofoto ČR以JPG图形栅格格式进行分发，分发单元按SM 5分幅设置，每个单元对应实地覆盖范围为2.5千米×2千米。
